Answer: If I were president, I would make healthcare more affordable.
Step-by-step explanation:
We are given the following sentence: "If I was president I will make health care more affordable."
We can immediately see an issue with the clauses. The first half of the sentence is in the past tense, signified by "was" and the later half is in the future tense, the issue becomes more prevalent when we recognize that the sentence itself revolves around a hypothetical.
By saying the word "will" it essentially acts as a guarantee for the scenario at hand. But with a change of words to "would" it better fits in the context of the sentence that revolves around a hypothetical an "if scenario".
Using this newfound information we would arrive at the sentence: If I were president, I would make healthcare more affordable. | Justifiable through the notion that while you are not entirely sure it would happen it is a suggestion as to what you would do if it happened.
